A Quick And Painless Guide To Virtual Private Networks (Vpn)

A Virtual Private Networks would signify a network inside another network. This is a form of technology most popular with companies whose staff works independently. So in essence, we are looking at the network provided by the World Wide Web used in a new and creative way. The framework of the Internet, in effect, is used by the employees working remotely to get into their corporate systems.

All corporate entities feel the need these days to ramp up security. This is achieved by creating a VPN (virtual private network) on top of the normal internet connection. This type of connection allows for greater security and encryption. This makes it impossible for anybody to stop data from being transferred and only allows network access to those authenticated users.

So as you can see, the VPN (virtual private network) is a private network inside a public one, being the one created through the Internet.

So how exactly does this process work? First of all, you need a corporate server replete with the requisites of a good server setup – including a firewall and fully installed server VPN software. The second ingredient would be client VPN software installed on the computers of the remote employees. After the client computer goes on the Internet, the VPN client software would communicate with the corporate VPN server and begin the authentication process. Access would then be granted after the server is able to successfully identify the connecting client as a valid user. In essence, this is the recipe for a hard outer shell of protection and encryption, and after access has been granted, information can pass to and from the virtual private network freely and safely.

One last benefit you can enjoy from a VPN or leased line would be additional savings. Leased lines can increase in price based on the geographic distance between sites. This is the opposite of a virtual private network where gauging the price can be done more realistically.

It does not matter whether you run a small or large business, but if you have remote employees and the need to access different remote sites, then VPN would be worth considering.

This is VPN in a nutshell, explained in simple English. This is not an article written by an IT professional and should not be misconstrued as professional advice, but rather as a quick guide to gauge this technology’s feasibility for your needs. So for further reading and research, you should always consider the specific type of implementation – is it site-to-site, remote or secure dial-up? Other interesting topics worth reading include, but are not limited to firewalls, encryption, security, different types of servers and Internet protocol security protocol, or IPSEC.
